SKYLIGHT AND FLOORLGHT CONSTRUCTION.

Application filed May 25, 1925. Serial No. 32,625.

lily intention relates to a novel skylight or tloorlight construction,wherein l employ lens holders or metal shields et a novel constructionhaving outer walls, which con- G verge downwardly and are provided withinner upwardly extending inwardly coni verging flanges upon the upperedges oi which are seated the lenses or glass units, preferably ofrollen, wired, annealed glass, the V-shaped inner seat which is formedbetween the outer and inner walls of the lens holders forming a pocketfor the reception of sealing and cushioning material, which alsowaterproo'fs all points of glass Contact, while the outer surface of theinner inclined lens supporting flange is protected by maus or concrete,whose upper edge is coincident with the top ot said inner tlange and thebottom oit the wired rolled, annealed glass unit or lens whereby thelens holders or metal shields are entirely concealed and protected bythe cement and will not be liable to ri'ist, oorrode or deteriorateunder any condition et use.

lily invention further consists ot a novel marmer and method otassembling the lens holders or metal shields, the rolled, wired, orannealed glass lenses and t-he templates below the-in whereby when theconcrete is poured into said templates it will not only slfuround thecontiguous outer walls of the lens holders and will not only engage thebeads therein, but said concrete will also tlow upwardly around therounded edge and the contiguous outer wall of the lens supportingflange, so that the parts after the concrete has set will be eeetivelyprotected 'trom rust or corrosion.

.it further consists ot other novel features ot construction andadvantage, all as will he hereinatter described and pointed out in theclaim appended hereto.

lfor the purpose ot illustrating' my invention, l, have shown in theaccompanying drawings forms thereotl which are at present preterred byine, since they will give .in practice satisfactory and reliable resultsalthough it is to be understood that the various instrumentalitics oitwhich my invention consists can be variously arranged and organized andthat my invention is not limited to the precise arrangement andorganiz/,ation ot these instrulnentahties as herein shown and described.

Figure l represents a perspective view of a lens holder in detachedposition embodying my invention.

Figure 2 represents on an enlarged scale, a sectional perspective viewshowing the manner of assembling the lens holders, the rolled, wired,annealed glass lenses and the templates prior to the pouring ot theconcrete.

Figure 3 represents on an enlarged scale, a vertical sectional view or aportion ont the finished frame, showing particularly the concrete asinclosing and sealing the surfaces of the inner inclined lens supportingdange.

Similar numerals ol' reference indicate corresponding parts in thefigures.

ln carrying out my invention in the production of my novel product, Iemploy a lens holder l of rect-angular or other contour, having thedownwardly and inwardly converging side walls 9, whose lower edges arerounded as at 3, and provided with the upwardly extending inner lip orflange 4l, whereby a V -shaped inner poclret 5 is produced,'the extentand position of said pocket being` best understood 'from Figures 2 andd. |he upper edge of the flange a which is continuous and extendsentirely around the lens holder, as will be understood from Figure l,serves as a support for the lens otl rolled or wired glass G, the wiremesh therein being indicated at 7, and being omitted desired. 8designates the sealing compound which occupies the space above thepocket 5, and effectively incloses the edges of the wired glass lens G.

9 designates the concrete, and it) the reinforcing bars therein, itaeing noted that the upper outer surface ll ot the inclined flange 4l otthe lens holder is completely surrounded by the .cement at the pointsl2. This construction or collocation ot the con crete with respect tothe lens holder is ellected by the template 13 made in two sections 14.split at the point l5, as seen in Figure 2.

In the assembly of the elements producing my novel device, the lensholders or metal shields l are arranged substantially 'as seen in Figure2, and the rolled or wired glass, annealed lenses or units are placed inposition upon the top edges ot the inner flanges et.

The reinforcements l0, which in practice are square steel rods extendingiongitudinally and transversely and of the proper sizes required for thevarious spans and the template sections lll, having been placed inpesition, the concrete 9 is next poured into the templates and ait'terthe concrete has set, the assembled elements prior to the removal of thetemplates will appear is seen in Figure 2, the sealing compound orcushion 8 having been poured into place at any suitable stage.

Upon the removal of the template sections ll, the parts will appear asseen in Figure 3, whereby it vill be seen that the mass of concrete atthe outer top portions as indicated at l2, completely encloses the outersurfaces ll ot the lens sumiorting` flange Llso that the entire surfaceol the lens holder and; particularly said lens supporting,` flange fl isentirely conceal-ed and surrounded on its under side by the concrete, sothat all liability ol rust, corrosion and deterioration of the lensholder by exposure to the air is entirely obviated.

The metal shields or lens holders l in practice entirely surround eachlens or wired glass unit 6 for its lull depth, ther f providing aperfect protection against pres-- sure of the concrete caused byexpansion.

rlhe. lenses or glass units 6 composed either of rolled or wired,annealed which can be quickly replaced for convenience of makinglrepairs with unskilled labor, said lenses or glass units 6 being` inprac` tice cut from either rolled, annealed yglass or annealed, rolled,wired glass, which are cut to the. desired contour at any desired stagein the manu-facture of the sheet.

By my present construction and by the utilization or rolled, annealedwired, glass lenses having the characteristics described, a muchstronger and more durable construe tion than heretofore is produced, andif a lens becomes shattered or broken it can be removed from` its lensholder or metal shield by unskilled labor and readily replaced with anew one, so that the elliciency and durability oi' the construction canat all times be maintained at a minimum of cost. The rolled, annealedlenses can be removed without injuring the reinforced concretetramework, since said lenses are carried by their respective metalliclens holders, which are not liable to injury when a broken glass isbeing` removed.

llhe wired glass lenses (l can be made from waste from rolled annealedsheets, lor which at the present time there is no use, and the rolledsheet glass itself is much cheaper than pressed or molded glass, and inaddition the rolled sheet glass being` ot a more uniform thicknessenables a more uniform annealing than can be obtained in pressed ormolded glass, which is usually of uneven thickness and contour.

The method of construction, whereby the concrete is caused. entirely tosurround the contiguous portions of the shield l, particularly theflange t, enables me to produce a superior character of work, and thereare no parts olf the flange l exposed to the air, so that the liabilityol rust and corrosion thereof is entirely obviated. rlhe ribs or beadslll are effectively interlocked in the concrete is evident.

lit will now be a parent that I have devised a novel and usefulvskylight and lioorlight construction, which embodies the lieatures ol'advantage enumerated as desirable in the statement of the invention andthe above description, and while l have, in the present instance, shownand described preferred embodiments thereof which will give in practicesatisfactory and reliable results, it is tobe understood that the saineare susceptible ot modilication in various particulars withoutdeparting,- from the spirit or scope ot the invention or sacrilicing anyof its advantages.

Having thus described my invention, what claim as new and desire tosecure by Letters Patent, is:

The hereindescribed skylight, sidewalk, or iloorlight consti' ction,which consists olf a metal lens holder, a rolled annealed lens supportedthereon, and a bottom covering ot concrete completely covering thebottoni of said lens holder and extendingl to the bottom olsaid lens,whereby corrosion of said lens holder is pr vented.
